===How Web 2.0 can help with EPrints repositories===

+

+

Web 2.0 Facilities such as commenting, bookmarking and tagging facilitate the generation of a large 'social' dataset, which can help researchers to connect with the kind of information that they seek much more efficiently. This is especially helpful in today's world, where the amount of information available to researchers is unprecedented.

+

+

===Web 2.0 facilities could be===

+

+

*Handled within the repository, so that (for example) items can be ranked by the number of comments, or their digg-style 'score'. The advantage of this is that the data is decentralised - control is not ceeded to some third party provider. The disadvantage is that the data is distributed between different repositories and it might be difficult to make sound inferences from the relatively small amount of data that resides on any one particular repository.

+

+

*Handled by external services like Digg, del.icio.us or Connotea (are already in some EPrints repositories) . The advantage of this approach is that there is little complexity in the repository itself, but equally, there is little benefit (value add) that the repository can offer the user.

+

+

+

+

===Ways that Social Data Could be Managed Handled Within EPrints===

+

+

The accumulated commenting and tagging data that such an approach gathers might be better managed in a separate user area - the user has their own area of the database where their comments an their tags are stored. There is already a user dataset in EPrints - perhaps its role needs to be enlarged.

+

+

Alternatively, these items can be managed as a separate table (by separate processes and user interfaces and services if necessary) and EPrints can just interpret the fields in the table as if they were readonly eprint metadata.

+

+

On the other ''other'' hand, EPrints can provide a category of metadata items that behave as normal (accessible through the standard API and user interface) but don't trigger changes in the metadata history or last-changed time. After all, an article doesn't change just because someone rates it.

===='''APML''' (Attention Profiling Markup Language)====

+

''APML allows users to share their own personal Attention Profile in much the same way that OPML allows the exchange of reading lists between News Readers. The idea is to compress all forms of Attention Data into a portable file format containing a description of ranked user interests.'' - [http://www.apml.org/ apml.org]

+

+

So, APML acts as a track record of what you have been interested in socially across several sites during the last however many days. This ''attention profile'' could conceiveably be used as a way for helping social applications to fine-tune just what kind of relevant information they want to push at the profilee.

===='''OpenSocial''' (An API from Google)====

+

'' The web is more interesting when you can build apps that easily interact with your friends and colleagues. But with the trend towards more social applications also comes a growing list of site-specific APIs that developers must learn.''

+

+

''OpenSocial provides a common set of APIs for social applications across multiple websites. With standard JavaScript and HTML, developers can create apps that access a social network's friends and update feeds. ''

The EDSPACE project is developing a user-centric approach to learning object repository.

OpenSocial provides a common set of APIs for social applications across multiple websites. With standard JavaScript and HTML, developers can create apps that access a social network's friends and update feeds.
